Stabilization of MOS-FET type voltage to current converters

A power dissipative system for testing a power supply having first and second output terminals using test conductors having inductive properties, said power dissipation system comprising:

• (1) a plurality of closed loop voltage to current converters each having first and second load terminals wherein said first load terminals are connected to each other and said second load terminals are connected to each other;
• (2) a circuit having a capacitance connected across said first and second load terminals;
• (3) a plurality of correction signal generators each corresponding to one of said voltage to current converters, responsive to said power supply, said correction signal generators each providing an output signal as a function of voltage generated across one of said first or second inductance;
• and
• (4) a plurality of summing circuits each responsive to a corresponding output signal of one of said correction signal generators and further responsive to a command signal, output of each one of said summing circuits controlling the current flow of corresponding current converter.

A method for providing a stable electronic load for a power supply having first and second output terminals using test conductors having inductive properties, said method comprising the steps of:

• (1) providing a closed loop voltage to current converter with first and second load terminals for connection via said test conductors to said tested power supply;
• (2) connecting a capacitance across said first and second load terminal;
• (3) providing a correction signal responsive to said power supply as a function of voltage generated across one of said first or second inductances;
• and
• (4) coupling said correction signal to a summing circuit responsive to a command signal, output of said summing circuit controlling the current flow of said current converter.
